Question

formula for refraction at plane surface a)n1u =n2v b)n1n2 =uv c)n1v=n2u d)n1/n2 =v/u
please tell me immediately ​

Answer 1

Answer:

answer is c

Explanation:

we know n1/ n2 = u/v

Answer 2

Answer:

Option : C

Explanation:

Light enters from medium-1 to medium-2. Here, θ1 is the angle of incidence and θ2 is the angle of refraction.
